Corrosion Control

Steel is a fantastic material; - strong, flexible, abundant and relative inexpensive. However, it has one major enemy; - its tendency to easily and quickly corrode. The corrosion rate increases with temperature, presence of salt, humidity, certain acids and stresses. The result for marine assets is near optimum conditions for corrosion losses and any ship or oil & gas asset will quickly deteriorate and fail without proper Corrosion Control.

MSI has delivered hands-on solution to Corrosion Control onboard since 1995 and our teams of experienced professionals will ensure that protective coatings are applied and repaired as needed to protect the underlying asset.

In Shipping, the an old-school rule of thumb has been that steel replacement is 10x more costly than shielding it with a corrosion protective coating. For offshore structures – and in particular for those in tropical climates – the cost of neglected corrosion protection can be 50 to 100x the cost of steel renewal.

To effectively control corrosion, it is important to repair protective coatings early to prevent localized failures to develop into corrosion hot-spots. Especially in submerged situations, spot damages to coating steel structures tend to act as an anode and are quickly beyond class minimums.

MSI will inspect the vessel or unit and recommend cost-effective but quality repairs to maintain the structural integrity and the full design life-time of the asset.

Fabric Maintentance

Equally important for shipping clients as for oil & gas clients, a planned approach to Fabric Maintenance will ensure full availability of the vessel or unit and help the client avoid unplanned down-time and unnecessary ship yard stays.

Besides a comprehensive program of Corrosion Control, Fabric Maintenance focuses on planned maintenance of all surface areas and include remedies for typical issues such as heat damage around flares, pipe supports and U-bolts, corrosion under insulation, FPSO modules, anode and ICCP systems and tanks particularly prone to coating damage such as slop tanks and produced water tanks.

MSI can handle all fabric maintenance requirements on ships and offshore oil & gas units. We have efficient solutions for water ballast tanks, decks, accommodations/engine casings, hull above the water line, pipes and pipe supports, production modules, cargo domes on LNG vessels and all other internal and external surfaces on these ships and units.

The MSI teams are multi-skilled and are certified riggers/scaffolders, UHP blasters and spray painters to ensure that you have a minimum of crew changes and that the work can proceed smoothly without unnecessary changes in the crew onboard.

Life Extensions

Requests for life-extensions on oil & gas units such as FPSO’s are becoming common as advances in reservoir management and recovery rates have together with new near-by fields being served by existing production systems have added years to the earlier life-expectancy of oil & gas fields.

With ship yard repairs out of the question, FPSO are being upgraded on station and years of valuable life is added to the units to economically get the last drop of viable oil out of the ground.

MSI have key roles in a number of life-extensions on both FPSO’s and LNG tankers. As a main contractor on steel and coating repairs, MSI is able to plan and coordinate the work to get the most out of the limited FOB availability which is almost always a major constraint onboard.

Using MSI Project Management experience, your life-extension project will be tightly monitored and planned and unplanned events will be optimally handled regardless if the project is large or small.

Steel Repairs

As a result of Fabric Maintenance and a regular feature in any life-extension project, steel repairs or renewals will almost always be required.

MSI can provide certified welders for any size job onboard from welding up a few cracks to replacing tons of steel.
In cargo, slop and ballast tanks.

Where cost effective, we install SPS overlays to strengthen problem areas such as below class minimum main deck plate thickness.

Material handling and access issues are always major obstacles to any onboard steel repairs. MSI has solutions and experience to make sure all steel jobs get completed in full compliance with the clients HSEQ requirements and according to class rules.

Inspections & Consultancy

MSI has a team of professional steel and coating inspectors who can assist with evaluating, planning and completing class approved repairs on schedule and on budget.

We work with major oil companies and large ship owners to inspect and develop repair specifications, budgets and repair standards and we attend the dockings or onboard repairs to ensure they get done according to specification and on budget.

Periodic inspections allows a fleet-wide Fabric Maintenance program to function properly as there is almost always several ships or units needing attention and limits from budgets and POB issues. Proper and common inspections ensures that the limited resources are targeted the most appropriate asset and that the client gets the most out of its Fabric Maintenance Budget.

Special Projects

MSI has carried out life-extension projects on 2nd hand floating docks (steel construction). These were large projects replacing hundreds of tons of steel and extending crinolines and otherwise adopting the docks to modern operations with systems such as hydraulic ship support systems.

MSI also carries out pipe repairs on smaller bore piping systems such as heating coils on tankers and FPSO’s and renewal of hydraulic lines for valves and other systems onboard.

As part of life-extension projects on FPSO’s, MSI also provides multi-skilled teams carrying our refurbishment of existing living quarters and construction of additional living space on existing decks or in separate containers. The teams include steel and coating specialists, floor installers, carpenters and marine electricans, pipe-fitters and HVAC specialists.

Passive Fire Protection

MSI has years of experience applying high tech fire-retardant coatings to electrical power cables on high value ships and offshore and onshore oil & gas units. MSI AS can supply experienced specialist for all kind of Passive Fire protection projects certified by Lloyds, DNV and product suppliers such as Jotun and International Paints.

When exposed to fire, almost all materials lose their structural strength. Steel, for example, supports less weight, while concrete tears and wood carbonizes.
Passive fire proofing coatings help both supporting and statically loaded structures to maintain their integrity longer. These coatings save lives, because emergency exits, utility shafts, stairways, and roof structures remain accessible longer for emergency teams and fire fighters.
The two most important categories in fire proofing coatings are cementitious and intumescent systems.

Working with leading suppliers of Passive Fire Protection coatings, MSI is continually working for a range of vessels which include the leading cruise lines, major LNG ship owners and major oil & gas companies both shore-side and onboard the vessels.

Using IRATA qualified teams of rope access painters, MSI can carry out most passive fire protection projects without erecting any scaffolding. This speeds up the work and minimizes the time onboard and the costs to the clients.
